AULACORHAMPHUS. 561 
Hab. Mexico, Sacatepec (Boucard °), Amula in Guerrero (Mrs. H. H. Smith ®). 
A green Toucan in the Museum at Munich was supposed by Wagler to belong to 
the same species he had previously named Pteroglossus pavoninus in Berlin. Their 
distinctness was discovered by Sturm, and the Munich bird named P. wagleri. Some 
confusion has arisen concerning the application of these names, but we are now 
convinced that Wagler’s name P. pavoninus belongs to Aulacorhamphus prasinus and 
not to the present bird, though we thought otherwise in 1889 4. 
Of A. wagleri very little is known. Besides the original specimen, which no doubt 
came from Mexico, only two others have been recorded ; one of these was obtained by 
M. Boucard at Sacatepec °, and is now in the British Museum. The other formed part 
of a large collection made for us by Mrs. H. H. Smith, when she, in company with 
her husband, explored the mountain-range traversing the Mexican State of Guerrero 
called the Sierra Madre del Sur; it is a female and was shot near a place called 
Amula, in the higher part of the range. 
A. wagleri is more distinct from A. prasinus than appears at first sight, for besides 
the difference of the colouring of the base of the bill, the dark edging of the tomia runs 
nearly parallel to the edge instead of arching over it. The forehead is tinged with 
yellowish at the base of the feathers, and the sides of the neck and the throat washed 
with blue. The swollen margin to the base of the maxilla, too, is much wider and 
more prominent.
